Answer to Question #141280 in Physical Chemistry for maryana

Question

5. Describe the function of a salt bridge. What would happen if the half-cell compartments of a galvanic cell were not connected?

Answer 1

Solution.

A salt bridge is a contact between electrolyte solutions. Without it, the electrochemical reaction would not have occurred. The salt bridge is filled with potassium chloride or agar-agar. Through it, ions are transferred from one electrolyte solution to another. In the case of a Jacobi-Daniel galvanic cell, zinc ions are transferred from the anode electrolyte to the cathode. And the sulfate ions pass from the cathode electrolyte to the anode one.
